中文摘要:在对武陵山复杂构造带主要残留向斜油气地质条件调查的基础上,通过油气成藏主要参数的对比,提出了注重沉积与构造保存的选区评价思路,优选了安场向斜有利区并布署实施安页1井钻探工程。该井二叠系栖霞组油气显示活跃,含气层厚147m;在志留系石牛栏组钻遇多个高压气层,首次在南方该层系海相灰岩获得高产天然气流,并见到少量稠油;在上奥陶统五峰组-下志留统龙马溪组钻获高含气碳质页岩近20m,达到了页岩气商业开发的标准,进一步扩大了我国南方页岩气商业勘探范围;在奥陶系宝塔组钻遇高压气层,首次在南方该层系获得天然气发现。

Breakthrough of Paleozoic Marine Strata in Wuling Mountain Complex Tectonic Zone
Abstract:On the investigation of Petroleum geology conditions of the residue syncline in Wuling Mountain complex structure belt, By contrast hydrocarbon reservoirs main parameters, sedimentary and tectonic saved evaluate ideas constituency was proposed, Preferably the An Chang syncline favorable zone and Anye-1 wells was deployed. Active oil and gas shows in Permian Qixia formation, gas-bearing thicknessof up to 147 meters. Multiple high pressure gas reservoir were drilled in Silurian Shiniulan formation which is the first time get high-yield gas flow in this formation in southern China and a small amount of heavy oil was found. Nearly 20m high gas-bearing carbonaceous shale was drilled in the Upper Ordovician Wufeng formation - Lower Silurian Longmaxi formation.It reached the commercial development of shale gas standards, which further expand the scope of commercial exploration of shale gas in southern China. In addition, high pressure gas reservoir was drilled in Ordovician Baota formation which is also the first discoveryed.
